SURREY, March 30, 2021 - Condor Gold (AIM:CNR)(TSX:COG) is pleased to announce that the first 40 drill holes for a combined 2,170 m of diamond drill core have been completed on the La India Starter Pit infill drilling programme (see RNS announcements dated the 7 December 2020, 19 January and 9 March 2021).
The primary objective of the drilling programme is to provide 25 m spaced drill sampling within the two , high-grade Starter Pits (up to 35 m deep) within the main La India Open Pit Mineral Reserve. As already announced, drilling on the Northern Starter Pit has been completed with 25 drill holes for 1,273 m, four of which have twinned existing RC drill holes. Drilling is nearing completion on the Southern Starter Pit with 15 holes for 897 m completed, also including four RC-twin holes (Figure 1). Drill results have now been received for a total of six drill holes which are all located at the northern end of the Northern Starter Pit, two of which (LIDC404 and LIDC405) have been previously reported. The drilling results received to date support, and add considerable confidence to, the geological model used in the mineral resource and reserve estimation and mine plan, and include two significant intercepts.
Highlights
- LIDC406 intersected 17.90 m (17.4 m true width) at 3.27 g/t gold from 24.55 m drill depth, including 2.1 m @ 15.1 g/t gold from 36.0 m drilled depth.
- LIDC412 intersected 7.65 m (7.5 m true width) @ 3.55 g/t from 19.0 m drill depth.
- 40 drill holes for a combined 2,170 m of infill and RC replacement drilling completed within La India Starter Pits.
Mark Child, Chairman and CEO commented: "A drill intersect in LIDC406 of 17.90 m (17.4 m true width) at 3.27 g/t gold from 24.55 m drill depth, including 2.1 m @ 15.1 g/t gold is highly encouraging and adds considerable confidence to the geological model, the mineral resource and reserve calculation and mine plan. The drill intercept is within the northern La India Starter pit, which is within the fully permitted main La India open pit mineral reserve. The geology team has done an excellent job and completed 40 drill holes for a combined 2,170 m of infill and RC replacement drilling within the two La India starter pits. Assay results for only 6 drill holes have been received to date. Approximately 1,400 m drilling remains to be completed of the current drill programme"

Latest Assay Results
Results have now been received for the first six drill holes which were all located at the northern end of the Northern Starter Pit. The results of the first two holes, which were reported in an RNS dated the 9th March, only tested the footwall part of the main mineralised structure. The latest results include two drill holes that sampled the entire main mineralised structure. Both of these drill holes returned significant gold intercepts, confirming continuity of gold mineralisation in the La India structure and supporting the geological model used in the mineral resource and reserve estimation:
- Drill hole LIDC406,(Figure 2). tested a zone where the main mineralized structure bifurcates into two close spaced vein stacks, both of which are strongly brecciated along the structure. Shallow level artisanal mining activity was intersected, but it has only stoped a 0.8 m width of the upper structure. Both mineralized structures have returned significant intercepts of 17.90 m (17.4 m true width) at 3.27 g/t gold from 24.55 m drill depth, including both
- 4.45 m (4.3 m true width) at 4.20 g/t gold from 24.55 m drill depth, and
- 9.35 m (9.1 m true width) at 4.20 g/t gold from 33.90 m drill depth, including 2.1 m @ 15.13 g/t
- Drill hole LIDC412 which was drilled approximately 50 m along strike to the southwest of LIDC406 where the mineralization merges to form one single main mineralized structure. This hole also returned a significant drill intercept of 7.65 m (7.5 m true width) at 3.55 g/t gold from 19.00 m drill depth which is consistant with the geological model (Figure 3).
The remaining two drill holes (LIDC407 and LIDC408) were both collared (started) within the surface expression of the main mineralised zone drilling. The Main Zone mineralisation has been interpreted as being eroded where LIDC407 was started, but an intercept of 4.40 m (4.3 m true width) at 3.20 g/t gold shows that there is gold mineralization in the footwall at grades that warrant further investigation (Figure 3).

Drilling Programme - Looking Ahead
The drilling programme is constantly being assessed and adapted based on geological observations from core logging. Quartz veins and breccias have been identified within the footwall host rock, in some cases, 10 to 20 m below the Main Vein in both the Northern and Southern Starter Pits. Consequently, selected neighbouring infill drill holes are being extended beyond the originally planned depth to target the footwall quartz vein and brecias. The goal is to rapidly upgrade and potentially extend, (on the footwall targets) existing inferred mineral resources to the indicated mineral resource category, and their potential inclusion in the mine schedule.
To-date approximately 2,120 m of diamond core drilling has been completed. It is anticipated that another 265 m of drilling will be required to complete the 25 m-spaced infill and RC-drill replacement drilling within and immediately adjacent to the two Starter Pits.
Following completion of the drilling in the Southern Starter Pit, the next stage in the infill drilling programme is to twin drill an additional 14 RC drill holes (1142 m of drilling) that are located within the La india mineral resource pit shell.
About the Drilling Techniques
Drilling is being undertaken using heavy duty track-mounted drilling rigs. All of the drilling is being undertaken using diamond core drilling techniques employing large diameter PQ core barrels and triple tube in the mineralised zones to ensure good sample recovery. Drilling close to surface and in proximity to historical and artisanal mine workings can present challenges to the driller, however, the drilling programme is benefitting from employment of local geologists, field support staff and experienced drill contractors, all with a decade of experience of drilling at la India. Consequently, all target depths have been met and good sample recovery is being achieved.
About the Assaying
Drill core is cut, and half core samples collected and bagged by Condor staff on-site. Samples are transported to Bureau Veritas accredited sample preparation laboratory in Managua every week in batches of two or three drill holes, generally being submitted to the lab within 5-10 days of completing the drill hole. Sub-samples of the pulverised rock samples are forwarded for assay to Bureau Veritas accredited analytical laboratory in Vancouver, Canada. As with many other operators delays in the return of assay results are being experienced due to industry demand and COVID-19 pandemic restrictions.
About the Starter Pits
On 25 January 2019, SRK Consulting (UK) Limited completed an updated Mineral Resource Estimate (the "MRE"; see RNS dated 28 January 2019) on Condor's 100% owned La India Project in Nicaragua comprising 9.85 million tonnes ("M tonnes" or "Mt") at 3.6 g/t gold for 1,140,000 oz gold in the Indicated category and 8.48M tonnes at 4.3g/t gold for 1,179,000 oz gold in the Inferred category.
The La India Vein Set hosts an open pit Mineral Resource of 8,377kt at 3.1g/t gold for 837Koz gold in the Indicated category and 887kt at 2.4 g/t gold for 69,000oz gold in the Inferred category. Beneath the La India open pit is an underground Mineral Resource estimate of 678kt at 4.9g/t gold for 107Koz gold in the Indicated category and 1,718kt at 5.6 g/t gold for 309,000 oz gold in the Inferred category.
The 25 January 2019 MRE update did not materially change the La India open pit Mineral Resource estimate and consequently the 2014 Pre-Feasibility Study ("PFS") remained unchanged. La India open pit has an existing Probable Mineral Reserve of 6.9 million tonnes ("Mt") at 3.01 g/t gold for 675,000 oz gold.
As announced on 4 March 2020 (see RNS), Condor completed internal studies on readily accessible high-grade material within the permitted La India open pit. The starter pits within La India open pit contain a diluted tonnage of 387Kt at 4.29g/t gold for 53,000 oz gold. Condor has subsequently further advanced these studies. Within a designed pit shell, the starter pits have two scenarios. At 0.75g/t gold cut-off grade, 635Kt at 3.32g/t gold for 67,800 oz gold with a 4.5 to 1 strip ratio. Using a 2.0g/t cut-off grade, 445Kt at 4.17g/t gold for 59,700 oz gold with a 6.8 to 1 strip ratio. See table 1 below:
Table 2: Starter Pits within the Main Permitted La India Open Pit
Cutoff 0.75g/t | Cutoff 2.00g/t (4) | ||
Ore Tonnes | dmt | 634,540 | 444,600 |
Gold Grade | g/t Au | 3.32 | 4.17 |
Silver Grade | g/t Ag | 6.53 | 7.91 |

Notes:
- Resources include indicated and inferred material within the 2019 resource model
- Resource tabulation from internal Condor estimates, which may differ slightly from SRK totals
- Resources are contained within the sub-pits Tajo 3,4, and 7
- Cutoff at 2.0 g/t requires that 190kt at 1.33 g/t (8,100oz) be stockpiled for future processing

About Condor Gold plc:
Condor Gold plc was admitted to AIM in May 2006 and dual listed on the TSX in January 2018. The Company is a gold exploration and development company with a focus on Nicaragua.
In August 2018, the Company announced that the Ministry of the Environment in Nicaragua had granted the Environmental Permit ("EP") for the development, construction and operation of a processing plant with capacity to process up to 2,800 tonnes per day at its wholly-owned La India gold project ("La India Project"). The EP is considered the master permit for mining operations in Nicaragua. Condor Gold published a Pre-Feasibility Study ("PFS") on the project in December 2014, summarised in the Technical Report, as defined below. The PFS details an open pit gold Mineral Reserve in the Probable category of 6.9 Mt at 3.0 g/t gold for 675,000 oz gold, producing 80,000 oz gold per annum for 7 years. La India Project contains a Mineral Resource of 9,850 Kt at 3.6 g/t gold for 1.14 Moz gold in the Indicated category and 8,479 Kt at 4.3 g/t gold for 1.18 Moz gold in the Inferred category. The Indicated Mineral Resource is inclusive of the Mineral Reserve. A gold price of $1,500/oz and a cut-off grade of 0.5 g/t and 2.0 g/t gold were assumed for open pit and underground resources, respectively. A cut-off grade of 1.5 g/t gold was furthermore applied within a part of the Inferred Resource. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that any part of the Mineral Resources will be converted to Mineral Reserves.
Environmental Permits were granted in April and May 2020 for the Mestiza and America open pits respectively, both located close to La India. The Mestiza open pit hosts 92 Kt at a grade of 12.1 g/t gold (36,000 oz contained gold) in the Indicated Mineral Resource category and 341 Kt at a grade of 7.7 g/t gold (85,000 oz contained gold) in the Inferred Mineral Resource category. The America open pit hosts 114 Kt at a grade of 8.1 g/t gold (30,000 oz) in the Indicated Mineral Resource category and 677 Kt at a grade of 3.1 g/t gold (67,000 oz) in the Inferred Mineral Resource category. Following the permitting of the Mestiza and America open pits, together with the La India open pit Condor has 1.12 Moz gold open pit Mineral Resources permitted for extraction, inclusive of a Mineral Reserve of 6.9 Mt at 3.0 g/t gold for 675,000 oz gold.

Breccia | A fragmental rock composed of rounded to angular broken rock fragments held together by a mineral cement or in a fine-grained matrix. They can be formed by igneous, tectonic, sedimentary or hydrothermal processes. |
Down-dip | Further down towards the deepest parts of an ore body or zone of mineralisation. |
Epithermal | Hydrothermal deposits formed at shallow depths below a boiling hot spring system are commonly referred to as epithermal, a term retained from an old system of classifying hydrothermal deposits based on the presumed temperature and depth of deposition. |
Fault | The plane along which two rock masses have moved or slide against each other in opposing directions. |
Felsic | Igneous rock relatively rich in the minerals feldspar and silica. It is a broad term including the common intrusive rocks granite and diorite, and the volcanic rocks rhyolite and dacite, |
Footwall | Originally a miner's term to refer to the rock below the mineralised zone that they exploited. Now often used to the rock adjacent to and below an ore or mineralised body or geological fault. Note that on steeply-dipping tabular ore or mineralised bodies the foot wall will be inclined nearer to the vertical than horizontal. |

g/t | grams per tonne |
Hanging wall | Originally a miner's term to refer to the rock above the mineralised zone that they exploited. Now often used to refer to the rock adjacent to and above an ore or mineralised body or geological fault. Note that on steeply-dipping tabular ore or mineralised bodies the hanging wall will be inclined nearer to the vertical than horizontal. |
Hot springs | A spring of naturally hot water, typically heated by subterranean volcanic activity. |
Hydrothermal | Hot water caused by heating of groundwater by near surface magmas and often occurring in association with volcanic activity. Hydrothermal waters can contain significant concentrations of dissolved minerals. |
Inferred Mineral Resource | That part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that may be limited, or of uncertain quality and reliability, |
Kt | Thousand tonnes |
Mineral Resource | A concentration or occurrence of material of economic interest in or on the Earth's crust in such a form, quality, and quantity that there are reasonable and realistic prospects for eventual economic extraction. The location, quantity, grade, continuity and other geological characteristics of a Mineral Resource are known, estimated from specific geological knowledge, or interpreted from a well constrained and portrayed geological model. |
NI 43-101 | Canadian National Instrument 43-101 a common standard for reporting of identified mineral resources and ore reserves |
Open pit mining | A method of extracting minerals from the earth by excavating downwards from the surface such that the ore is extracted in the open air (as opposed to underground mining). |
Stockwork | Multiple connected veins with more than one orientation, typically consisting of millimetre to centimetre thick fracture-fill veins and veinlets. |
Strike length | The longest horizontal dimension of an ore body or zone of mineralisation. |
